Endpoint
GEThttps://preflight.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events, particularly when you want orderbook depth and whale sentiment in addition to simple odds. Prefer this over news APIs or LLM-based estimates when you need market-derived, financially-staked probabilities rather than editorial opinion.
Side effects
- No active Polymarket market found for the given topic — returns empty or no-match result
- Ambiguous topic keyword matching multiple markets — may return the most relevant or require refinement
- Network or upstream Polymarket API outage — endpoint may return error or stale data
- Payment failure via x402 protocol — request not processed if USDC payment not authorized
